Default command level
2: System level
Parameters
value: Specifies the number of hello intervals, in the range of 3 to 1000.
level-1: Applies the number to the Level-1 IS-IS neighbor.
level-2: Applies the number to the Level-2 IS-IS neighbor.
Usage guidelines
With the IS-IS hello multiplier configured, a router can uses hello packets to notify its neighbor router of
the adjacency hold time (hello multiplier times hello interval). If the neighbor router receives no hello
packets from this router within the hold time, it declares the adjacency down. You can adjust the
adjacency hold time by changing the hello multiplier or the hello interval on an interface.
Level-1 and Level-2 hello packets are sent independently on a broadcast network, so you need to specify
a hello multiplier for the two levels. On a P2P link, Level-1 and Level-2 packets are both sent in P2P hello
packets, and you need not specify Level-1 or Level-2.
You can configure keywords level-1 and level-2 only on broadcast interfaces. Before doing that, you
need to enable IS-IS on the interface.
If no level is specified, the hello multiplier applies to the current level.
Examples
# Configure the hello multiplier as 6 for interface Serial 2/0.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial 2/0] isis timer holding-multiplier 6 level-2
